Ellen DeGeneres welcomes
Pamela Anderson on her show Thursday (Nov. 7) to apologize for not believing in her when
she said a few weeks ago that she'd be running the New York City Marathon to raise money for Haiti.

"It is time for a segment called "The 1st Ever I was Wrong by Ellen DeGeneres," says the host. "I may have accidentally said [Pamela Anderson] would not finish [the New York City Marathon]. More than once. ... please welcome New York City Marathon finisher Pamela Anderson."

Anderson also debuts her new pixie haircut on "Ellen," a look she says she stole from the talk show host.

"I just thought my hair had a life and I wanted to kind of put that behind me and start fresh and I thought it would be good for the marathon and it was," says Anderson.

"You look fantastic. I love it. Let's talk about that you did it and congratulations you did it in five hours and?" asks DeGeneres.

"And forty-one minutes, which is a long time. ... Yeah, I finished, it was hard. It was those last five miles, it was like giving birth. ... It was like giving birth and then being told to run as you're giving birth," says Anderson. "It was so much pain in my hips. I don't know if women are meant to run, especially after having kids, but we raised a lot of money for Haiti for our JPA trial."

The JPA trial she speaks of is the J/P Haitian Relief Organization, which aims to save lives and bring sustainable programs to the Haiti following the earthquake of 2010.
